Description of Related Art

Cellular damage due to oxidative stress caused by reactive oxygen species (ROS) has been demonstrated to be involved in the onset or progression of various chronic diseases, e.g., cardiovascular disease, including arteriosclerosis and hypertension; diabetes and diabetic related complications, such as glomerular nephropathy; cerebral nerve degenerative diseases, such as Alzheimer's disease, Parkinson's disease, ALS (amyotrophic lateral sclerosis) and multiple sclerosis; asthma, chronic obstructive pulmonary disease, skin diseases, eye diseases, and cancer. Enhancing the capability of protecting from oxidative stress may be useful in one or more of preventing these diseases, delaying their progress, or delaying their onset. Further, with the varied etiology associated with this diverse set of diseases, a general strategy to mitigate oxidative stress would be beneficial.

The basic biochemistry of a cell generates ROS, including superoxide anions, hydroxyl anions, nitric oxide, peroxynitrite, and hydrogen peroxide. All of these products serve critical cellular signaling needs, but also have deleterious effects if overproduced or left unchecked. Many disease conditions induce persistent levels of ROS that are associated with the establishment of chronic pathophysiologic changes seen within a variety of tissues. These complications, in and of themselves, may be the primary drivers of disease morbidity and mortality.

Under normal physiological conditions, production of ROS are counterbalanced by a well defined and conserved set of cellular pathways that respond to, limit, and repair the damage due to ROS. This adaptive set of genes, called the phase II system, encodes enzymes that degrade ROS directly (e.g., superoxide dismutase and catalase) as well as increase levels of a cell's endogenous antioxidant molecules, including glutathione and bilirubin. Examples of known phase II enzymes include glutathione S-transferase (GST), NAD(P)H:quinone oxidoreductase 1 (NQO1), glutamyl-cysteinyl ligase (GCL), heme oxygenase 1 (HMOX1), and thioredoxin reductase 1 (TXNRD1). A common sequence called antioxidant responsive element (ARE) is present in a promoter of each gene of these phase II enzymes, and its expression is induced by the transcription factor Nrf2 (NF-E2 related factor 2).

Of the phase II enzyme system, HMOX1 has been found to be a key component. The role of HMOX1 is to metabolize heme into bilirubin, carbon monoxide, and free iron, as a first step of a two-step process to catabolize heme. The first, and rate-limiting reaction, is the production of biliverdin and carbon monoxide from heme by HMOX1. The second step is the production of bilirubin from biliverdin by biliverdin reductase. Both bilirubin and carbon monoxide have been shown to scavenge ROS and to have potent anti-oxidant and anti-inflammatory activity. Agents that induce production of HMOX1 have been shown to have beneficial activity in models of diabetes, cardiovascular disease, hypertension, and pulmonary function.

HMOX1 is found in the liver, kidneys, spleen, and skin, of humans and has also been localized to specific cell types, notably fibroblasts and macrophages. HMOX1 exists in at least three isoforms, one constitutive and the other two inducible. Heme, heavy metal ions (e.g., tin, gold, platinum, and mercury), transition metal ions (e.g., iron, cobalt, chromium, and nickel), and electrophiles (e.g., natural products such as sulforaphane and curcumin) can all induce production of HMOX1. Induction of HMOX1 and other phase II genes are controlled by a number of transcription factors that are responsive to heavy metals, heme, and electrophiles. The transcription factors Nrf2, Bach1, and Maf are particularly important in this process. In addition, there are cofactors and regulatory molecules that are important in regulating Phase II gene induction. These include Keap1, an adapter molecule targeting Nrf2 for ubiquitination, and two mitochondrial proteins, DJ-1 and frataxin (FXN) that serve to augment Nrf2 activation in the presence of electrophiles. HMOX1 is also induced as part of a generalized stress response to stimuli such as thermal shock, oxidative stress and cytokines such as interleukin-1 (IL-1), tumor necrosis factor and IL-6. The stress response is seen as beneficial in that it results in protection of vulnerable cell enzymes from inactivation.

BRIEF DESCRIPTION OF DRAWINGS

Not applicable

DETAILED DESCRIPTION

The following definitions are intended to clarify the terms defined. If a particular term used herein is not specifically defined, the term should not be considered to be indefinite. Rather, such undefined terms are to be construed in accordance with their plain and ordinary meaning to a person of ordinary skill in the field(s) of art to which the invention is directed.

As used herein the term “alkyl” refers to a straight or branched chain saturated hydrocarbon having one to ten carbon atoms, which may be optionally substituted, as herein further described, with multiple degrees of substitution being allowed. Examples of “alkyl” as used herein include, but are not limited to, methyl, ethyl, n-propyl, isopropyl, isobutyl, n-butyl, sec-butyl, tert-butyl, isopentyl, n-pentyl, neopentyl, n-hexyl, and 2-ethylhexyl.

The number carbon atoms in an alkyl group is represented by the phrase “C_(x-y) alkyl,” which refers to an alkyl group, as herein defined, containing from x to y, inclusive, carbon atoms. Thus, C₁₋₆ alkyl represents an alkyl chain having from 1 to 6 carbon atoms and, for example, includes, but is not limited to, methyl, ethyl, n-propyl, isopropyl, isobutyl, n-butyl, sec-butyl, tert-butyl, isopentyl, n-pentyl, neopentyl, and n-hexyl.

As used herein, the term “alkylene” refers to a straight or branched chain divalent saturated hydrocarbon radical having from one to ten carbon atoms, which may be optionally substituted as herein further described, with multiple degrees of substitution being allowed. Examples of “alkylene” as used herein include, but are not limited to, methylene, ethylene, n-propylene, 1-methylethylene, 2-methylethylene, dimethylmethylene, n-butylene, 1-methyl-n-propylene, and 2-methyl-n-propylene.

The number of carbon atoms in an alkylene group is represented by the phrase “C_(x-y) alkylene,” which refers to an alkylene group, as herein defined, containing from x to y, inclusive, carbon atoms. Similar terminology will apply for other terms and ranges as well. Thus, C₁₋₄ alkylene represents an alkylene chain having from 1 to 4 carbons atoms, and, for example, includes, but is not limited to, methylene, ethylene, n-propylene, 1-methylethylene, 2-methylethylene, dimethylmethylene, n-butylene, 1-methyl-n-propylene, and 2-methyl-n-propylene.

As used herein, the term “cycloalkyl” refers to a saturated, three- to ten-membered, cyclic hydrocarbon ring, which may be optionally substituted as herein further described, with multiple degrees of substitution being allowed. Such “cycloalkyl” groups are monocyclic, bicyclic, or tricyclic. Examples of “cycloalkyl” groups as used herein include, but are not limited to, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, norbornyl, and adamantyl.

The number of carbon atoms in a cycloalkyl group will be represented by the phrase “C_(x-y) cycloalkyl,” which refers to a cycloalkyl group, as herein defined, containing from x to y, inclusive, carbon atoms. Similar terminology will apply for other terms and ranges as well. Thus, C₃₋₁₀ cycloalkyl represents a cycloalkyl group having from 3 to 10 carbons as described above, and for example, includes, but is not limited to, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, norbornyl, and adamantyl.

As used herein, the term “heterocycle” or “heterocyclyl” refers to an optionally substituted mono- or polycyclic saturated ring system containing one or more heteroatoms. Such “hetercycle” or “heterocyclyl” groups may be optionally substituted as herein further described, with multiple degrees of substitution being allowed. The term “heterocycle” or “heterocyclyl,” as used herein, does not include ring systems that contain one or more aromatic rings. Examples of heteroatoms include nitrogen, oxygen, or sulfur atoms, including N-oxides, sulfur oxides, and sulfur dioxides. Typically, the ring is three- to twelve-membered. Such rings may be optionally fused to one or more of another heterocyclic ring(s) or cycloalkyl ring(s). Examples of “heterocyclic” groups, as used herein include, but are not limited to, tetrahydrofuran, tetrahydropyran, 1,4-dioxane, 1,3-dioxane, piperidine, pyrrolidine, morpholine, tetrahydrothiopyran, and tetrahydrothiophene, where attachment can occur at any point on said rings, as long as attachment is chemically feasible. Thus, for example, “morpholine” refers to morpholin-2-yl, morpholin-3-yl, and morpholin-4-yl.

As used herein, when “heterocycle” or “heterocyclyl” is recited as a possible substituent, the “heterocycle” or “heterocyclyl” group can attach through either a carbon atom or any heteroatom, to the extent that attachment at that point is chemically feasible. For example, “heterocyclyl” would include pyrrolidin-1-yl, pyrrolidin-2-yl, and pyrrolidin-3-yl. When “heterocycle” or “heterocyclyl” groups contain a nitrogen atom in the ring, attachment through the nitrogen atom can alternatively be indicated by using an “-ino” suffix with the ring name. For example, pyrrolidino refers to pyrrolidin-1-yl.

As used herein the term “halogen” refers to fluorine, chlorine, bromine, or iodine.

As used herein, the term “oxo” refers to a >C═O substituent. When an oxo substituent occurs on an otherwise saturated group, such as with an oxo-substituted cycloalkyl group (e.g., 3-oxo-cyclobutyl), the substituted group is still intended to be a saturated group.

As used herein the term “haloalkyl” refers to an alkyl group, as defined herein, that is substituted with at least one halogen. Examples of branched or straight chained “haloalkyl” groups as used herein include, but are not limited to, methyl, ethyl, propyl, isopropyl, n-butyl, and t-butyl substituted independently with one or more halogens, for example, fluoro, chloro, bromo, and iodo. The term “haloalkyl” should be interpreted to include groups such as —CF₃, —CH₂—CF₃, and —CF₂Cl.

As used herein, the term “aryl” refers to a six- to ten-membered cyclic, aromatic hydrocarbon, which may be optionally substituted as herein further described, with multiple degrees of substitution being allowed. Examples of “aryl” groups as used herein include, but are not limited to, phenyl and naphthyl. As used herein, the term “aryl” also includes ring systems in which a phenyl or naphthyl group is optionally fused with one to three non-aromatic, saturated or unsaturated, carbocyclic rings. For example, “aryl” would include ring systems such as indene, with attachment possible to either the aromatic or the non-aromatic ring(s).

As used herein, the term “heteroaryl” refers to a five- to fourteen-membered optionally substituted mono- or polycyclic ring system, which contains at least one aromatic ring and also contains one or more heteroatoms. Such “heteroaryl” groups may be optionally substituted as herein further described, with multiple degrees of substitution being allowed. In a polycyclic “heteroaryl” group that contains at least one aromatic ring and at least one non-aromatic ring, the aromatic ring(s) need not contain a heteroatom. Thus, for example, “heteroaryl,” as used herein, would include indolinyl. Further, the point of attachment may be to any ring within the ring system without regard to whether the ring containing the attachment point is aromatic or contains a heteroatom. Thus, for example, “heteroaryl,” as used herein, would include indolin-1-yl, indolin-3-yl, and indolin-5-yl. Examples of heteroatoms include nitrogen, oxygen, or sulfur atoms, including N-oxides, sulfur oxides, and sulfur dioxides, where feasible. Examples of “heteraryl” groups, as used herein include, but are not limited to, furyl, thiophenyl, pyrrolyl, oxazolyl, thiazolyl, imidazolyl, isoxazolyl, isothiazolyl, 1,2,4-triazolyl, pyrazolyl, pyridinyl, pyridazinyl, pyrimidinyl, indolyl, isoindolyl, benzo[b]thiophenyl, benzimidazolyl, benzothiazolyl, pteridinyl, and phenazinyl, where attachment can occur at any point on said rings, as long as attachment is chemically feasible. Thus, for example, “thiazolyl” refers to thiazol-2-yl, thiazol-4-yl, and thiaz-5-yl.

As used herein, when “heteroaryl” is recited as a possible substituent, the “heteroaryl” group can attach through either a carbon atom or any heteroatom, to the extent that attachment at that point is chemically feasible.

As used herein, the term “heterocyclylene” refers to an optionally substituted bivalent heterocyclyl group (as defined above). The points of attachment may be to the same ring atom or to different ring atoms, as long as attachment is chemically feasible. The two points of attachment can each independently be to either a carbon atom or a heteroatom, as long as attachment is chemically feasible. Examples include, but are not limited to,

where the asterisks indicate ponts of attachment.

As used herein, the term “heteroarylene” refers to an optionally substituted bivalent heteroaryl group (as defined above). The points of attachment may be to the same ring atom or to different ring atoms, as long as attachment is chemically feasible. The two points of attachment can each independently be to either a carbon atom or a heteroatom, as long as attachment is chemically feasible. Examples include, but are not limited to,

where the asterisks indicate ponts of attachment.

Various other chemical terms or abbreviations have their standard meaning to the skilled artisan. For example: “hydroxyl” refers to —OH; “methoxy” refers to —OCH₃; “cyano” refers to —CN; “amino” refers to —NH₂; “methylamino” refers to —NHCH₃; “sulfonyl” refers to —SO₂—; “carbonyl” refers to —C(O)—; “carboxy” or “carboxyl” refer to —CO₂H, and the like. Further, when a name recited multiple moieties, e.g., “methylaminocarbonylmethyl”, an earlier-recited moiety is further from the point of attachment than any later-recited moieties. Thus, a term such as “methylaminocarbonylmethyl” refers to —CH₂—C(O)—NH—CH₃.

As used herein, the term “substituted” refers to substitution of one or more hydrogens of the designated moiety with the named substituent or substituents, multiple degrees of substitution being allowed unless otherwise stated, provided that the substitution results in a stable or chemically feasible compound. A stable compound or chemically feasible compound is one in which the chemical structure is not substantially altered when kept at a temperature from about −80° C. to about +40° C., in the absence of moisture or other chemically reactive conditions, for at least a week, or a compound which maintains its integrity long enough to be useful for therapeutic or prophylactic administration to a patient. As used herein, the phrases “substituted with one or more . . . ” or “substituted one or more times . . . ” refer to a number of substituents that equals from one to the maximum number of substituents possible based on the number of available bonding sites, provided that the above conditions of stability and chemical feasibility are met.

As used herein, the various functional groups represented will be understood to have a point of attachment at the functional group having the hyphen or dash (−) or an asterisk (*). In other words, in the case of —CH₂CH₂CH₃, it will be understood that the point of attachment is the CH₂ group at the far left. If a group is recited without an asterisk or a dash, then the attachment point is indicated by the plain and ordinary meaning of the recited group.

When any variable occurs more than one time in any one constituent (e.g., R^(d)), or multiple constituents, its definition on each occurrence is independent of its definition on every other occurrence.

As used herein, multi-atom bivalent species are to be read from left to right. For example, if the specification or claims recite A-D-E and D is defined as —OC(O)—, the resulting group with D replaced is: A-OC(O)-E and not A-C(O)O-E.

As used herein, the term “optionally” means that the subsequently described event(s) may or may not occur.

As used herein, “administer” or “administering” means to introduce, such as to introduce to a subject a compound or composition. The term is not limited to any specific mode of delivery, and can include, for example, intravenous delivery, transdermal delivery, oral delivery, nasal delivery, and rectal delivery. Furthermore, depending on the mode of delivery, the administering can be carried out by various individuals, including, for example, a health-care professional (e.g., physician, nurse, etc.), a pharmacist, or the subject (i.e., self-administration).

As used herein, “treat” or “treating” or “treatment” can refer to one or more of delaying the progress of a disease or condition, controlling a disease or condition, delaying the onset of a disease or condition, ameliorating one or more symptoms characteristic of a disease or condition, or delaying the recurrence of a disease or condition or characteristic symptoms thereof, depending on the nature of a disease or condition and its characteristic symptoms.

As used herein, “subject” refers to any mammal such as, but not limited to, humans. In one embodiment, the subject is a human. In another embodiment, the subject is a human who exhibits one or more symptoms characteristic of a disease or condition. The term “subject” does not require one to have any particular status with respect to any hospital, clinic, or research facility (e.g., as an admitted patient, a study participant, or the like).

As used herein, the term “compound” includes free acids, free bases, and any salts thereof. Thus, phrases such as “compound of embodiment 1” or “compound of claim 1” refer to any free acids, free bases, and any salts thereof that are encompassed by embodiment 1 or claim 1, respectively.

As used herein, the term “pharmaceutical composition” is used to denote a composition that may be administered to a mammalian host, e.g., orally, topically, parenterally, by inhalation spray, or rectally, in unit dosage formulations containing conventional non-toxic carriers, diluents, adjuvants, vehicles, and the like. The term “parenteral” includes subcutaneous injections

As used herein, “substituted fused imidazole derivatives” refers to compounds encompassed by Formula (I), described below.

In one embodiment, the present invention provides a pharmaceutical composition comprising the compound of Formula (I) or a pharmaceutically acceptable salt thereof.

In another embodiment, the present invention provides a pharmaceutical composition comprising a compound of any one of embodiments 1 to 271 (recited above). In another embodiment, the pharmaceutical composition comprises a compound of any one of embodiments 1 to 271 and a pharmaceutically acceptable carrier, excipient, diluent, or a mixture thereof.

In an embodiment, the pharmaceutical compositions containing a compound of Formula (I) or a pharmaceutically acceptable salt thereof may be in a form suitable for oral use, for example, as tablets, troches, lozenges, aqueous, or oily suspensions, dispersible powders or granules, emulsions, hard or soft capsules, or syrups or elixirs.

Compositions intended for oral use may be prepared according to any known method, and such compositions may contain one or more agents selected from the group consisting of sweetening agents, flavoring agents, coloring agents, and preserving agents in order to provide pharmaceutically elegant and palatable preparations. Tablets may contain the active ingredient in admixture with non-toxic pharmaceutically-acceptable excipients which are suitable for the manufacture of tablets. These excipients may be for example, inert diluents, such as calcium carbonate, sodium carbonate, lactose, calcium phosphate or sodium phosphate; granulating and disintegrating agents, for example corn starch or alginic acid; binding agents, for example, starch, gelatin or acacia; and lubricating agents, for example magnesium stearate, stearic acid or talc. The tablets may be uncoated or they may be coated by known techniques to delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monostearate or glyceryl distearate may be employed. They may also be coated by the techniques described in U.S. Pat. Nos. 4,356,108; 4,166,452; and U.S. Pat. No. 4,265,874, to form osmotic therapeutic tablets for controlled release.

In another embodiment, formulations for oral use may also be presented as hard gelatin capsules where the active ingredient is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin, or a soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium, for example peanut oil, liquid paraffin, or olive oil.

In another embodiment, the composition may comprise an aqueous suspension. Aqueous suspensions may contain the active compounds in an admixture with excipients suitable for the manufacture of aqueous suspensions. Such excipients are suspending agents, for example sodium carboxymethylcellulose, methylcellulose, hydroxypropylmethylcellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia; dispersing or wetting agents may be a naturally-occurring phosphatide such as lecithin, or condensation products of an alkylene oxide with fatty acids, for example polyoxyethylene stearate, or condensation products of ethylene oxide with long chain aliphatic alcohols, for example, heptadecaethyl-eneoxycetanol, or condensation products of ethylene oxide with partial esters derived from fatty acids and a hexitol such as polyoxyethylene sorbitol monooleate, or condensation products of ethylene oxide with partial esters derived from fatty acids and hexitol anhydrides, for example polyethylene sorbitan monooleate. The aqueous suspensions may also contain one or more coloring agents, one or more flavoring agents, and one or more sweetening agents, such as sucrose or saccharin.

Also, oily suspensions may be formulated by suspending the active ingredient in a vegetable oil, for example arachis oil, olive oil, sesame oil or coconut oil, or in a mineral oil such as a liquid paraffin. The oily suspensions may contain a thickening agent, for example beeswax, hard paraffin or cetyl alcohol. Sweetening agents such as those set forth above, and flavoring agents may be added to provide a palatable oral preparation. These compositions may be preserved by the addition of an anti-oxidant such as ascorbic acid.

Dispersible powders and granules suitable for preparation of an aqueous suspension by the addition of water provide the active compound in admixture with a dispersing or wetting agent, suspending agent and one or more preservatives. Suitable dispersing or wetting agents and suspending agents are exemplified by those already mentioned above. Additional excipients, for example, sweetening, flavoring, and coloring agents may also be present.

The pharmaceutical compositions of the invention may also be in the form of oil-in-water emulsions. The oily phase may be a vegetable oil, for example, olive oil or arachis oil, or a mineral oil, for example a liquid paraffin, or a mixture thereof. Suitable emulsifying agents may be naturally-occurring gums, for example gum acacia or gum tragacanth, naturally-occurring phosphatides, for example soy bean, lecithin, and esters or partial esters derived from fatty acids and hexitol anhydrides, for example sorbitan monooleate, and condensation products of said partial esters with ethylene oxide, for example polyoxyethylene sorbitan monooleate. The emulsions may also contain sweetening and flavoring agents.

In another embodiment, the pharmaceutical compositions of the present invention may comprise a syrup or elixir. Syrups and elixirs may be formulated with sweetening agents, for example glycerol, propylene glycol, sorbitol or sucrose. Such formulations may also contain a demulcent, a preservative and flavoring and coloring agents. The pharmaceutical compositions may be in the form of a sterile injectable aqueous or oleaginous suspension. This suspension may be formulated according to the known methods using suitable dispersing or wetting agents and suspending agents described above. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally-acceptable diluent or solvent, for example as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, and isotonic sodium chloride solution. In addition, sterile, fixed oils are conveniently employed as solvent or suspending medium. For this purpose, any bland fixed oil may be employed using synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables.

The pharmaceutical compositions of the present invention may also be in the form of suppositories for rectal administration of the compounds of the invention. These compositions can be prepared by mixing the drug with a suitable non-irritating excipient which is solid at ordinary temperatures but liquid at the rectal temperature and will thus melt in the rectum to release the drug. Such materials include cocoa butter and polyethylene glycols, for example.

In an embodiment, for topical use, creams, ointments, jellies, solutions of suspensions, etc., containing the compounds of the invention may be employed. For the purpose of this application, topical applications shall include mouth washes and gargles.

In an embodiment, the compounds of Formula (I) and pharmaceutically acceptable salts thereof may also be administered in the form of liposome delivery systems, such as small unilamellar vesicles, large unilamellar vesicles, and multilamellar vesicles.

General Experimental Section

LC-MS data are obtained using gradient elution on a parallel MUX™ system, running four Waters® 1525 binary HPLC pumps, equipped with a Mux-UV 2488 multichannel UV-Vis detector (recording at 215 and 254 nM) and a Leap Technologies HTS PAL Auto sampler using a Sepax GP-C18, 4.6×50 mm; 5 micron particle-size column. In general, a three minute gradient is run from 25% B (97.5% acetonitrile, 2.5% water, 0.05% TFA) and 75% A (97.5% water, 2.5% acetonitrile, 0.05% TFA) to 100% B. The system is interfaced with a Waters Micromass ZQ mass spectrometer using electrospray ionization. MassLynx software is employed. All MS data were obtained in the positive mode unless otherwise noted. The reported m/z data are generally accurate within about ±1 for the M+ ion.

¹H NMR data were obtained on a Varian® Mercury 400 MHz spectrometer and chemical shifts were referenced using either the residual solvent proton signal (e.g., residual CHCl₃ in CDCl₃) or the TMS signal as an internal reference. Microwave heating procedures were used in some experiments and, in these cases, a Discover® microwave synthesis system (CEM, Matthews, N.C., USA) was used which included the use of pressurized glass reaction vessels at elevated temperatures.

All reagents and solvents including anhydrous solvents were commercially available and were used as received unless described otherwise. Any solutions of Grignard reagents and organolithium reagents were commercially available and were used as received and at the concentrations listed on their labels. Reactions are stirred using a magnetic stirring apparatus and magnetic stir bar in most cases. All reactions using air-sensitive reagents were run under inert gas. For reactions not heated using a microwave-generating apparatus, the reaction temperatures reported in the experimental section refer to the temperatures of an oil bath or cooling bath placed around a reaction vessel. For reactions performed using a microwave-generating apparatus, the temperatures refer to the temperatures reported by the microwave apparatus.

Biological Assay

Cell Culture.

Normal Human Fibroblast (NHLF), were obtained from Lonza. Cultures of cells were maintained in Fibroblast Growth Medium (FGM-2) medium supplemented with 2% fetal bovine serum (FBS), Fibroblast Growth Factor (hFGF-B) 0.5 mL, Insulin 0.5 mL, gentamicin/amphotericin-B 0.5 mL at 37° C. in a humidified atmosphere of 5% CO₂. Cells were grown to 80% confluence before treating.

HMOX1 Protein Assay.

NHLF cells were grown to 80% confluency and harvested by washing once with HEPES and then trypsinized. Equal numbers (2×10³ cells per well) of NHLF cells were plated in 384 well optilux tissue culture (BD) plates. Cells were incubated overnight in FGM-2 medium prior to exposure to compound. Cells were treated with either vehicle (DMSO) or compound (dissolved in vehicle) for 16 h. Cells were washed 2× with 1×PBS and fixed with 4% Paraformaldyhyde for 15 min.

The fixed cells were then permeablized with 0.1% Triton X-100 and blocked with 5% BSA in 1×PBS 0.05% Tween-20 for 15 min. HO-1 antibody (abcam) was used for immunostaining at 1:300 dilution in 1% BSA in 1×PBS for 1 hour. Cells were washed 2× with 1×PBS and secondary antibody goat anti-mouse Alexa 488 1:400 dilution (Invitrogen); Hoechst 1:2000 (Invitrogen) in 1% BSA in 1×PBS for 1 hour. Plate was washed 5× with 1×PBS and read at Hoechst Ex.360 Em. 535; Alexa 488 Ex.480 Em. 535 using GE InCell 1000. Results analyzed using GE InCell Analyzer software. Heme oxygenase data represents the fold change above DMSO treated cells.

Table 2, below, shows the fold change above DMSO for Examples 1 to 472. In general, the fold indiction data are reported for 5 μM concentration (i.e., p-moles of compound to total volume, where the solvent is about 99.2% media and 0.8% DMSO). In some instances, the reported data are for 3 μM concentration, which are indicated by an asterisk (*).
